Even the most opulent Beverly Hills home featured on Cribs can't even begin to compare to this half-hour tour of the International Space Station led by NASA ISS Commander Sunita Williams just hours before she returned to Earth on the Soyuz TMA-05M spacecraft.

It's a fascinating look at what life is like on the station, and reveals a lot of details about the astronaut's daily routine. Like their phonebooth-like sleeping quarters, the floating exercise bike that doesn't shake the station to pieces when they ride, and the Cupola observation module which provides stunning views of the Earth below. If you thought those space tourists who spent millions to visit the station were wasting their money, this will definitely change your mind. [YouTube via Coudal]
